Some here may be impressed, some won't. The ones who won't will base their lack of enthusiasm, rightly, on the fact that you did a sighted test of three sources. As a sighted test, your conclusions have no validity (not to sound too pedantic, sorry).
There are any number of problems. First, when you know what you are listening to, your biases toward equipment (brand name, type of device, etc.) will unconsciously affect your judgment about the sound. Second, unless you level-matched the devices (CD player, AVR) within at least .5 dB of each other, you aren't making any valid comparison. This must be done with a reasonably sensitive sound level meter. We know that if one source is perceptibly louder than another, people perceive the louder source as sounding "better". Third, you've really only tested two sources: the CD player and the AVR, because you are running two sources through the AVR's DAC. Fourth, you are controlling which source gets played when, so see 1 and 3, above. Fifth, it is extremely difficult to retain an accurate memory of sound in the time it takes to switch between two different sources. Differentiating among three? Almost impossible, unless at least one of the sources is broken or very poorly designed.
Look, we've all done what you've done. And, truth be told, we all do somewhat similar things even to this day, despite what we know. But we have to understand what conclusions are supportable, and what aren't.
